Study network performance analysis

Hi,

I have recently took interest in the "performance evaluation" side of computer networks, and am currently looking for bibliographical references/video courses/lecture notes teaching this stuff. I am particularly interested in IP traffic analysis and ATM networks performance evaluation.

For info, I come from a compsci background and would appreciate if the material deals, to some degree, with graph/probability theory. However, it doesn't have to be "theoretical-only": some practice in the form of study cases or other would be very welcome (using, for example, packet analysis and network simulation tools).

Thank you very much!
